I have high cholesterol, despite being on a diet for most of life as I am overweight. I have been taking Atorvastatin for approx 5 years and haven't had any side effects.
I have a family history of high cholesterol and heart problems and my younger brother died of a heart attack 5 years ago so I feel a bit like I am living on borrowed time. However according to the doctors white women do not have heart attacks and despite my family history and my own high cholesterol I virtually had to beg to go on to statins and get no follow up at all on this. A private medical originally showed up the problem but when the GP re-ran the tests a month later the results were much lower, personally I think they dumb down some of the results to control their costs as I have the same when they weigh me, nurse says I'm fine but my BMI says differently!
I watch what I eat and exercise regularly but it is the pills that keep it under control, if I forget for a while (as you have to take them at night) my cholesterol soon goes back up. A bit of research shows that some people actually over produce cholesterol, but its pointless talking to a GP about this as they just want you out of their office as quick as possible.
